SPECIFICATION forming part of Letters Patent No. 763,324, dated June 21, 1904.

Application filed January 12, 1904. Serial No. 188,705. (No model.)

T0 rtZZ wtfmt it mfr/,y concern:

Be it known that I, GEORGE l/VnsLnY RoB- ER'rs, a citizen of the United States, residing at Lemoore, in the county of Kings and State of California, have invented a new and useful Oultivator, of which the following is a speciiication.

This invention relates to cultivating implements; and it has for its object to provide a device of this class which shall be especially adapted to cultivating the soil in orchards and similar places for the purpose of stirring and agitating the soil, exterminating weeds, and the like.

This invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been shown a simple and preferred form of embodiment of my invention, it being understood, however, that I do not necessarily limit myself to the precise structural details therein exhibited, but reserve the right to such changes and modifications as may be resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same.

In said drawings, Figure 1 is a top plan view of a cultivating implement constructed in accordance with the principles of my invention. Fig. 2 is a longitudinal sectional view taken on the line 2 2 in Fig. 1. Fig. 3 is a transverse sectional view taken through the shaft carrying the rotary cultivating implcments.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The frame of my improved machine includes the axle 1, having transporting-wheels 2 2 and a tongue 3, which is securely connected with said axle by means of bolts 4 at the point of intersection and also by means of braces 5, which connect the rear portion of the tongue with the rear side of the axle. The latter supports a drivers seat 5. The rear end of the tongue has a vertical slot 6, in which is pivotally mounted a plate 7, the rear end of which has an upright 8, the upper end of which has a slot 9 for the reception of a pivoted rod 10, which extends forwardly and the front end of which is connected with a handlever 11,. which is fulcrumed to a block 12 upon the upper side of the tongue. The latter has a pair of uprights 13, supporting a plate 14, having a slot 15, through which the hand-lever extends, one edge of said slot being provided with ratchet-teeth 16, with any one of which the hand-lever may be placed in engagement. It will be seen that by operating said hand-lever the rear end of the pivoted plate 7 is capable of vertical adjustment and that by engaging said hand-lever with the ratchets 16 the said plate 7 may be retained at any position to which it may be adjusted.

The plate 7 is provided in rear of its pivotal-point with a transverse block 17, through which extends a shaft 18, the length of which exceeds that of the axle. The shaft 18 carries at each end a sleeve 19, mounted rotatively thereon and provided near the ends thereof with radiating arms 20, the outer ends of which carry earth-engaging cutters 21. l The latter are preferably disposed spirally around the sleeves 19, a result which is readily accomplished by placing the supportingarms 20 at either end of each sleeve somewhat out of alinement with each other. The cutters may be connected adjustably with the arms by means of bolts 22, engaging slots 23 in the blades or cutters, which may thus be readily adjusted, so as to properly engage the soil. The blades or cutters are also preferably formed with forwardly bent cutting edges 24. Upon the ends of the sleeves adjacent to the arms 2O are placed collars 25 to prevent said arms from becoming entangled with weeds, brush, and the like.

The operation of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. When the machine is propelled in a forward direction, the plate 7 may be lowered, so as to place the edges of the cutters in operative engagement with the slot, which will thus be cut, chopped, and agitated to an extent which will serve to successfully eradicate weeds and other undesirable growth. For transportation the plate 7 may be elevated by the means described until the cutting devices are suiiciently raised above the ground.

Having thus described my invention, I claiml. In a cultivating implement, a wheel-supported axle, a tongue securely connected with said axle and havinga rearward extension provided with a vertical slot, a plate mounted pivotally in said slot and having a transverse block, means for vertically adjusting the free rear end of the plate, a shaft mounted in the transverse block of the latter, and sleeves mounted upon said shaft and having radiating arms carrying earth-engaging blades.
